This Aloha shirt was purchased about 40 years ago. The material is 100% rayon. The size is men's M. It's a vintage item with a retro feel that evokes the era. Highly recommended for vintage clothing enthusiasts. I am also selling other vintage clothing purchased in the Showa era. Discounts are available for those considering purchasing multiple items. Stored at home. Will be shipped with simple packaging. I have inspected the item, but please understand that I may have overlooked any loose threads or stains.
